Description

[Detailed description of the invention] This invention uses plastic as the bottle material, and features a stretchable bellows part on the shoulder of the plastic bottle.
A spout pipe in the bottle is passed through a spout formed protruding from the top plate of the shoulder of the bottle and connected to the horizontal spout pipe, and an outer circumferential wall of the cap is fitted onto the spout. This container is characterized by its lower edge being brought into contact with the top plate of the bottle shoulder, which is lightweight in handling by taking advantage of the properties of plastic, and has an expandable bellows part on the bottle shoulder. By pressing and expanding and contracting the
It is intended to compress the inside of the bottle and easily pour out the contents.

To explain the embodiment of the present invention with reference to the drawings, a stretchable bellows part 3 is formed on the shoulder part 2 of a bottle 1 made of plastic material, and a spouting pipe 4 inserted into the bottle 1 is connected to the shoulder part 2 of the bottle 1.
The inside of the pouring spout 6 formed protrudingly formed on the top plate portion 5 is penetrated, and this is further connected to the horizontal pouring pipe portion 7.

The inner cylinder part 9 of the cap 8 is fitted into the spout 6, and the lower edge 10 of the outer peripheral wall of the cap 8 is brought into contact with the bottle shoulder top plate part 5.

In addition, when the bottle 1 of the present invention is made thin, the lower part 11 of the bottle may be held in a fitted state in a holder 12 having a required depth as shown in the drawing.

Since the present invention has such a configuration, when it is used, by pressing the cap downward in the direction of arrow A, the bellows part is contracted and internal pressure is applied, and the internal pressure is applied to the outside through the internal spouting pipe. The contents can be easily poured out from the pouring pipe section with extremely light operation, and the bottle material has the advantage of being easy to operate when the material is made thin, and the advantage of being provided at a low cost due to the reduction in the amount of material used. By combining these features, it is possible to provide a truly effective and suitable container of this type.
